If the density of air is \( \rho_a \) and that of the liquid \( \rho_l \), then for a given piston speed the rate (volume per unit time) at which the liquid is sprayed will be proportional to
1
\( \sqrt{\dfrac{\rho_a}{\rho_l}} \)
2
\( \sqrt{\rho_a \rho_l} \)
3
\( \sqrt{\dfrac{\rho_l}{\rho_a}} \)
4
\( \rho_l \)
